1. A fertility indicator for measuring and detecting the changes in body temperature of a human subject over a menstrual cycle, comprising:

  • a portable watch housing;

    clock timing means disposed in said housing for generating time-based signals;

    logic means disposed in said housing and connected to said clock timing means, and being responsive to said timebased signals for selecting combinations of said time-based signals, and for indicating the correct present time;

    a temperature sensor mounted on said watch housing and coupled to said logic means for measuring the body temperature of the human subject;

    solid state memory means having coded information command signals, and coupled to said logic means for sequencing said logic means to take a plurality of temperature readings at a preset real time, and to terminate the readings when the temperature has stabilized;

    data storage means for sequentially recording each of the stabilized temperatures that were measured during the menstrual cycle and analyzing the stored sequential temperature readings for determining the status of fertility;

    a plurality of colored lights responsive to said solid state memory means, for indicating the start of the menstrual period, the start of ovulation, and the completion of ovulation, respectively, after a preset time interval;

    display means responsive to said solid state memory means, and said data storage means for indicating the status of fertility of the subject during the menstrual cycle;

    alarm means coupled to said logic means and responsive to said clock timing means for indicating the real time for taking a temperature reading, and for indicating when the temperature has been recorded in said data storage means; and

    algorithm processing means disposed within said solid state memory means, for determining the status of the human subject from the temperatures recorded in said data storage means during the menstrual cycle, and predicting the time of ovulation by a predetermined time interval, measured from the next predicted menstrual period by comparison with the stored temperature record in said data storage means.
